interfacing LPDDR SDRAM to SDRC (OMAP3530)
am working on OMAP3530, i have selected LPDDR SDRAM of Part number MT46H256M32L4JV-6 IT, below figure shows an block diagram,
SDRC has 2 CS options and the LPDDR has 2 CS options.
my question is , OMAP3530 will support this LPDDR SDRAM?
Thanks and Regards
This LPDDR is supported by OMAP
Please refer section for you configuration in your data sheet mention here

Thank you very much,
i have to design a customized OMAP3530 board with 8Gbit (1GB) of LPDDR SDRAM and 32 Gbit (4GB) of NAND flash. as per your advice i will use same LPDDR SDRAM.
For NAND flash interface, i have selected MT29F16G16ADBCAH4-IT, some
few features are . . .
My question are ...
1) From OMAP3530 TRM doc, the section 22.214.171.124 NAND (Page Number 3397) shows that " Small page size (512 bytes + 16 bytes) and large page size (2048 bytes + 64 bytes)" but the selected data sheet shows "Page size x16: 2160 words (2048 + 112 words)". the OMAP 3530 will support this kind of NAND flash for Booting ?
2) From OAMP 3530 TRM doc, the section 126.96.36.199.1 Initialization and NAND Detection (Page Number 3399) shows the supported NAND flash devices ID's. Is it mandatory that to follow the same device id ? because am not getting exact Device id NAND flash.
3) The final requirement of NAND flash is 32 Gb, how to interface two NAND flash's of size 16Gb to GPMC?
Kindly Please help.......
Can you please share your datasheet?
i am attaching the data sheet for MT29F16G16ADBCAH4-IT,
I am not sure about the boot rom support for this nand flash, I have not found any match between the boot rom supported nand list
But i seems to be detect the first four blocks and give you the details as ID2 and boots.
Thanks for your response,
i have selected another NAND Flash (Part number is MT29F8G08ADBDAH4-IT ), which is 8Gb memory. please let me know wether this will support for booting or not?
If it supports, then how do i interface 2 or 3 NAND Flash's to GPMC?
this will support by omap
i have checked and found this nand (MT29F16G16ADBCA) will also supported by omap.
Thank you very much...
So i can use MT29F16G16ADBCA for booting as well as data storage device....
how do i interface 2 NAND Flash's to GPMC to make 4Gbyte?
actual requirement is 4Gbyte NAND Flash, in that 500Mbyte reserved for Linux OS Storage (Angstrom booting) and remaining can be used as Mass storage device.
You Can use another one chip select for connecting the second nand flash
